First you assume everyone...except ONE major bad guy is a minion.
One might generally assume that the label "BBEG" implies there will not be more than one, or perhaps two in an adventure. And there is more than one encounter in a day, at least the way most people play D&D.
Where in 4e is this assumption backed up, you sure are using alot of assumptions to back up your arguments here. and this just seems boring from a play perspective to only fight minions except for one fight.
You were the one who wanted simulation as opposed to "fun". Don't complain if exhaustive simulation turns out not to be fun.
Why is someone who uses trips, throws, disarms, locks and leverage to fight "annoying"? Sounds pretty imaginative, out of the box, and exciting to me. Remember the mantra of 4e... "Say yes". I mean how is this anymore annoying that a fighter who always wants to use his greataxe for better damage all the time or a rogue who wants to use ranged attacks all the time to avoid getting too close to enemies? It's called a fighting style.
See, there are shutdown powers and there are not-shutdown powers.
